Congratulations are in order for ShareASale merchant "Campus Book Rentals" for moving into the #1 position in the PowerRank 100 earlier this week. The back-to-school season must have provided the momentum to push them into the lead.

The PowerRank 100 is a representative ranking of the top performing merchants among the 3600+ currently in the SAS inventory. No one knows the "secret sauce" used to determine the rankings, and they are not indicative of how well each merchant may perform for a given affiliate. However, it is an impressive metric.

I'm sure Campus Book Rentals will be "looking over their shoulder" because the top rankings are always a moving target. It is good to see the Leaderboard change every so often - indicating that seasonality and competition thrives in the affiliate marketing business.
